研究目的
Investigating the inner structure and morphology-performance relationship of organic solar cells using advanced neutron scattering techniques.
研究成果
Neutron scattering techniques provide unique insights into the complex morphology and fast dynamics in bulk-heterojunction organic solar cells, which are critical for optimizing their performance.
研究不足
The experiments require the rare resource of neutron beamtime at one of the neutron sources worldwide.
1:Experimental Design and Method Selection:
Utilized grazing incidence small angle neutron scattering (GISANS) and quasi-elastic neutron scattering (QENS) to study the morphology and dynamics of organic solar cells.
2:Sample Selection and Data Sources:
Studied thin films based on P3HT:PCBM and PTB7:PC71BM blends.
3:List of Experimental Equipment and Materials:
Neutron scattering techniques were employed, including GISANS and QENS.
4:Experimental Procedures and Operational Workflow:
GISANS experiments were performed at fixed wavelengths or in a time-of-flight mode (TOF-GISANS) using a wavelength band. QENS was used to study molecular dynamics.
5:Data Analysis Methods:
Data analysis involved fitting with models in the framework of the distorted wave Born approximation (DWBA) and the effective interface approximation.
